WILLIAM A. PRINGLE, 0F NIAGARA FALLS, NEW YORK, ASSIGNOR TO THE CARTER- CRUMIE CO., LIMITED, OF NIAGARA. FALLS, NEW YORK, A CORPORATION OF CANADA.

PRINTING APPARATUS.

To all whom it may concern:

Be it known that I, WILLIAM A. PRINGLE, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain Vnew and useful Improvements in Printin Apparatus, of which the followin is a ful, clear, and exact description, suc as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to printing mechanism, and more particularly to mechanism for effecting rinting upon traveling webs which are to be cut or folded into separate sheets adapted thereafter to be bound or otherwise fastened together in book form.

One of the objects of the invention is to provide improved means for numbering the sheets which are to be cut from or folded in the web.

Other ob'ects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

Serial No. 346,392.

Referring now to the drawings 8 indicates one of a pair of parallel walls which form journal supports for the several rolls of cylinders, said walls being attached to the frame of the printing press in any suitable manner as by clamp bolts 9. Veb C upon which the numbering device is to operate is fed from a suitable source of supply between drawing rolls 11 and 12, roll 11 being spring-pressed toward roll 12 by means of the retractile spring 13 and is capable of being swung therefrom to allow the web to be inserted by means of a handle 14. Web C then passes over roll 12 and between it and a similar drawing roll 15,. and is received between a printing couple constituted by a plate cylinder 16 and an impression cylinder 17, which effects printing of any desired inscription upon the traveling web. The web is then carried along impression cylinder 17 to be engaged by thenumbering devices carried upon a cylinder, which coacts therewith, the construction of which forms a part of the present invention. This numbering mechanism, which is best shown in Figs. 2 to 11 inclusive, comprises a cylinder 18 which has provided therein a longitudinally extending recess 19 adapted to receive a block or head 20 which forms a support for a group of numbering wheels. Head 20 has secured thereto at either end, in the present instance, by means of screws 21, a block 22 within each of which is provided a pair of oppositely disposed locking l walls of a recess'19 of the cylinder, and are y adapted to be projected into engagement with the walls of said notches by means of screws 25 having tapering or cone-shaped ends which, when engaginvr with the inner ends of the locking bolts, force them in an outward direction, thus locking the head securely within the Walls of the recess and holding the same immovable against dislodgment by the centrifugal force produced by the rotative movement of the cylinder.

Upon a shaft 26 journaled between the end walls of head 20 are journaled a plurality of numbering devices which comprise in the present instance wheels 27, each of which is provided upon its periphery with a series of raised members or types, ranging from 1 to O. Each of numbering wheels 27 has upon one of its lateral surfaces an integral ratchet wheel 28, the teeth ofwhich correspond in number with the raised type members upon the periphery of the wheel. Also ournaled upon shaft 26, in the present instance, are a pair of idler or dummy ratchet wheels 29 and 30, respectively, the purpose of which will be apparent hereinafter. The dummy ratchetwheels and the numbering wheels are rotated by means of a pawl member 31 provided with a plurality of teeth 32, which gradually increase in length from one end to the other, as shown in Fig. 11 of the drawings, one. of said teeth being provided for each of the several ratchet wheels of the numbering wheels, and for each of the dummy ratchet wheels.

The teeth of the several rat-Chet wheels rest against curved surfaces 32" and provided between one pair of adjacent teeth in each of the ratchet wheels is a relatively deep, substantially V-shaped slot 33, as is clearly shown in Figs. 8 and 10 of the drawings. The purpose of these slots is to allow a tooth of pawl member 31 to enter therein a sutlicient depth to permit the adjacent tooth to engage the ratchet wheel of the adjacent numbering wheel, it being understood that the left hand tooth, which is the longest, first operates upon its dummy ratchet wheel until the same has been actuated through a complete revolution, when said tooth, entering the V-shaped recess of that wheel, will permit the next shorter tooth to engage with the next ratchet wheel and move through a distance of one ratchet tooth. At the next actuation of member 31 the tooth, which has previously been received in the V-shaped slot, will be carried therefrom and will ride thereafter th-rough the remainder of the subsequent rotation on the curved surfaces which separate the several teeth of the ratchet wheel. Thus, it will be seen that the second dummy ratchet wheel will be rotated through a space of one tooth upon each complete rot-ation of the outside ratchet wheel, and that the second ratchet Vwheel will actuate the first of numbering wheels 27 through a space of one tooth when it. has been rotated through a complete revolution. For instance, inasmuch as 10 teeth are provided in the outside dummy ratchet wheel, 10 revolutions thereof will cause one complete revolution of the adjacent dummy ratchet-wheel, which being also provided with 10 teeth will, when revolved 10 complete revolutions, allow the next shorter tooth of the ratchet member to engage a tooth of ratchet wheel upon the rst of said numbering wheels, and advance the same a single number. This construction, it will'be seen, allows a single number to be repeated a predetermined number of `times upon a traveling web, the mechanism in the present instance being set torepeat a single number 100 times. As will be apparent, however, the repetition of a single number may be varied at will by the withdrawal or insert-ion of the idler or dummy ratchet wheels, thereby allowing a given number to be repeated a greater or less number of times.

Pawl member 31 is pivotally carried upon a pair of hangers 34' journaled upon shaft 26, and is urged toward the numbering wheels by means of a spring 35. At one'end of head 20 in the upper portion thereof is provided a plate 36 provided witha pair of depending guide posts 37, which. enter vertical recesses 38.` extending through the head. Plate 36 is also provided with depending members39., the lower portions of which. are provided with. slots within which take. the pivots 40l of the pawl member 31, so that when plate 36 is raised by means of a: plunger 41 rigidly attached thereto and extending. downwardly through an opening 42 provided in the numbering: head, pawl member 31 will be carried forward and raised toactuate the numberingwheels. Plunger 41 is retracted to carry plate 364 in` a downward direction, andthe pawl member to a normal inoperative position, by means of av spring 43 which engagesa shoulder 44 of said plunger and exerts pressure against a fixed plate 45 or member screwed to the head beneath plate 36. .A

Engaging with each of the numbering wheels and dummy ratchet wheels is a pivotally mounted holding member 46, the upper end of which its exactly the curved sur-- faces 32 which separate the several teeth. These members prevent a reverse rotation orf the ratchet wheels, while allowingv arotation thereof in a normalY direction. Holding members 46A are spring pressed` toward the several ratchet wheels by means of a.V plate 47 which carries a plurality of independentrsprings 48. Membersl 46 also serve to hold the several numbering wheels in exact registry and determine exactly the position of the types with relation to the traveling web.

Located beneath the depending end' of plunger 41 in a longitudinally extending recess 49 of cylinder 18 is, in the present instance, a reciprocating strip 50, which carries a plurality of depending studsor plungers 51, each of which comprises a screw. threaded into said-strip. These screwsextend substantially through the cylinder, and are retracted to the position shown in Fig. 4 to hold strip 50 against the bottom wall of Vits recess by means of extensilesprings 52 coiled about said screws, which exert pressure against the heads` thereof, and'also against shoulders provided by av contracted opening through whichthe screws extend.

Located within a substantially square recess cut longitudinally in cylinder 18 is a block 53 within which is journaled a shaft 54, said block being held in position in its recess by means of clamp screws 55 which take against shoulders 56 provided thereon, as clearly shown in Fig. 5 of the drawings. Shaft 54 is provided intermediate its ends with a plurality of lingers 57, each of which is located beneath one of studs 5l, and upon the outer end of shaft 54 is an arm 58 rovided with an anti-friction roller 59. This anti-friction roller, when cylinder' 18 is rotated, rides over a cam 60 fast upon the frame of the machine, through which shaft 61 which carries the cylinder extends. Arm 58 when lifted by cam 60 rocks shaft 54 in block 53, and this shaft when rocked carries fingers 57 into engagement with studs 51 and lifts strip 50 within its recess. Ilunger 41 bein0engaged by strip 50 is forcibly projectec upward and actuates the numbering wheels in the manner above described. Thus, the numbering mechanism is caused positively to advance a number upon a predetermined number of rotations of the cylinder.

The web, after being acted upon by the numbering mechanism above described, is perforated by means of mechanism carried by the pair of mating cylinders 62 and 63 between which the web next passes.

The numbering head is inked by means of distributing rollers 74 and 75 which are in turn inked by a ductor 76 which is reciprocated by means of a lever 77, the upper end of which engages the shaft of the ductor. The lower end of lever 77 carries an antifriction roller 78 which runs over a cam 79 driven by means of pawl and ratchet mechanism. Pawl 80 of the pawl and ratchet mechanism is carried upon an arm 81 the opposite end of which has a slot which takes in a pin provided upon a gear wheel 83 secured upon the shaft 61 of cylinder 18. Impression cylinder 17 is driven by means of a driving gear wheel 84, and the several cylinders and rollers are connected by means of a train of gearing and driven with the required peripheral velocities, as shown in Fig. 1 of the drawings.

vWeb C may be of tissue paper or paper of any desired thickness, as will be obvious. Web C is also numbered at each rotation of cylinder 18 in a positive manner, as above described, and may also, if desired, be perforated by means of mechanism carried upon cylinders 62 and 63.

While in the resent instance I have shown the numbermg mechanism as adapted to repeat a single number a predetermined number of times, it will be obvious that by removing the idler or dummy ratchet Wheels the mechanism will number the sheets consecutively from 1 up, and that said mechanism may be set to number backward from any given number. It will accordingly be seenthat I have provided mechanism Wherein the numbering of the web is effected in an accurate and positive manner, and the construction of the perforating mechanism insures that the web shall not be torn or otherwise mutilated during the perforating operation.

As many changes could be made in the above construction and many apparently widely different embodiments of thls invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
